The bar chart illustrates the percentage of men working in senior development position in three different companies between 1980 and 2010.
Overall, the rate of men working in senior development position in IBM remained the lowest in the first five years and the opposite was true for the figure for Apple. However, the pattern was reversed at the end when IBM’s figure surged sharply over time while the percentage in Apple was more stable. Besides, Microsoft experienced a steady growth before finishing at a clear peak and it was the only company that was never the leading one among the three.
In 1980, IBM recorded the lowest proportion of men working in senior development, with only about 2% of employees in this position being male. The figure then levelled off after 5 years before soaring dramatically to over 10% in 1990. It continued to rise with significant gaps until the end and the largest increase occurred between 2000 and 2010, when the proportion rose by about 30%. Likewise, Microsoft also followed a similar upward trend when its figure started at roughly 8% then grew continuously but more marginally during the time and reached a clear peak in 2010 at approximately 45%.
Regarding the remaining company, Apple used to be the dominant company in that data among three in the first ten years. After dipping slightly from about 15% to about 12% between 1980 and 1990, the figure rebounded strongly to over 20% in 1995 although it can not recover its highest position. In 2010, Apple had only about 25% of men working in the senior development field, which was the smallest number in comparison with the others.
